Title: Image forming device
Inventor: KATSUMATA AKIO
IPC: G03G15/01
Filed: 1987-05-11
Abstract: PURPOSE:To immune the effect of the stain of a sensor and the variance of sensitivity and to reduce chromatic aberration by detecting and amplifying only the AC component of the detection signal of a pattern for measuring respective colors on a transfer belt and measuring the space of patterns. CONSTITUTION:When the pattern for measuring the chromatic aberration is detected in a reflection type sensor 27, only AC component of output current of a phototransistor Ph is fetched by a capacitor C2. The signal becomes the input of an inverted amplifier AMP2 through a voltage follower AMP1 and is amplified to be a proper voltage level. The output from the AMP2 is compared with a threshold voltage decided by resistances 8 and 9 by a comparator COMP1 so as to output a rectangular wave. By measuring the pitch of the rectangular wave output, the space of patterns transferred on a transfer belt can be known. Since only AC component of the output from the sensor is amplified to be used, the dislocation of picture can be reduced without receiving the effect of the stain of the sensor and the variance of sensitivity, etc.

Title: Cutting tool made of diamond-based extra-high pressure sintered material excellent in wear resistance and fracture resistance
Inventor: OHASHI CHUICHI
IPC: B23B27/14
Filed: 1994-05-26
Abstract: PURPOSE:To enhance wear resistance and fracture resistance by including a prescribed volume ratio of chromium carbonate as a dispersed phase formative element. CONSTITUTION:A cutting tool is formed by a diamond group extra-high pressure sintered material having a composition consisting of 1 to 20vol.% of dispersed phase in which chromium carbonate finely formed is uniformly distributed, and of the remainder of diamond which substantially forms the base. When the content of this dispersed phase is less than 1vol.%, the mutual binding accelerating action of diamond powders at the time of sintering is not sufficiently developed, and also desired excellent wear resistance and fracture resistance cannot be secured. On the other hand, when the content thereof exceeds 20vol.%, the ratio of the dispersed phase interposed between diamond grains becomes too much, and as a result the binding of the diamond grains is hindered, so that the formation of diamond base becomes difficult, and also the securement of excellent fracture resistance becomes difficult.

Abstract: PURPOSE:To contribute to environmental preservation and reuse of resources and enable simplification of equipment by a method wherein a resin-finished sheet material is formed into a corrugated sheet, which is put into a mold to heat and compress it so that the corrugated portions of the sheet are stretched, thereby forming the sheet into any shape. CONSTITUTION:Curved portions having corrugated shape 14 are formed on a resin- finished sheet material 10 in such a manner that the curved portions are formed into inclined, intersecting, or helical state or the like in all directions to form a corrugated sheet 16. In this case, the curved portions 14 are subjected to heating and compressing treatment at temperatures 120-200 deg.C and then cooled preferably to prevent the portions 14 from taking original shapes at ambient temperature. And to further improve drawing characteristics of the portions 14, moisture 18 is added to the sheet 16 to provide a wet state. In this manner, the corrugated sheet 16 with curved portions 14 thus prepared is put into a pair of molds 20,22 vertically disposed. And the molds 20,22 are heated to compress the sheet 16, while it is heated. As a result, the curved portions 14 of the sheet 16 is stretched so that a molded item having a shape corresponding to the shape of the mold surface is prepared.

IPC: C07C201/06
Filed: 1994-05-26
Abstract: PURPOSE: To safely obtain nitrophenol by nitrosating phenol in the presence of sulfuric acid under specified conditions and thereafter oxidizing p- nitrosophenol with nitric acid.  
     CONSTITUTION: Phenol is nitrosated with a nitrosating agent (such as sodium nitrite) in the presence of sulfuric acid of 60-90% conc. at 0-40°C. Then, p- nitrosophenol is oxidized with nitric acid. At that time the conc. of sulfuric acid is 50-80%, and p-nitrophenol is obtained by precipitation. The nitrosating agent is used in an amount of 150-300%, and a phenol: nitric acid molar ratio is 0.9-1.2. By keeping the sulfuric acid conc. constant during nitrosating and oxidizing reactions, p-nitrosophenol becomes soluble in the first step to avoide explosion of p-nitrosophenol and on the other hand p-nitrosophenol precipitated at the endpoint of the oxidizing step becomes soluble at a high conc.
